How to remove the Xubuntu Login screen in ubuntu 14.04

I have recently installed Xubuntu on my Ubuntu 14.04 desktop. So not a problem until I logged off, and i did not see my login screen but an ugly abnormal login screen (Xubuntu's Default)

Solution 1:

Open a terminal and run:

sudo apt-get remove lightdm-gtk-greeter && sudo apt-get install unity-greeter

This will remove xfce's greeter and make sure the default Unity one is installed.

Solution 2:

The best (and right) way to achieve that is configuring plymouth by running and selecting ubuntu-logo.plymouth:

sudo update-alternatives --config default.plymouth

Then you need to run:

sudo update-initramfs -u

Alternative to the two steps above, you can simply remove the plymouth-theme-xubuntu-logo package using apt-get, then the alternative will be chosen automatically.
